  • Publication number: 20240179255
    Abstract: A method and apparatus for processing documents is provided. The documents may be conveyed to a feeder for feeding documents to a scanner. The scanner scans each document to obtain image data and then discharges the document to one or more output or sort locations. The system may include a skew reduction assembly for reducing skew in the documents as the documents are fed to the scanner. The system may also include elements for improving image quality and reducing document damage while the document is scanned. The system may further include features for improving the stacking of the discharged documents.

  • Patent number: 5651664
    Abstract: A hydraulic pump apparatus (35) for a well assembly (36) including a rigid, elongated tubular casing (37). extending into a formation producing production fluid. The hydraulic pump apparatus (35) including an elongated tube (40) and a bottom-hole assembly (42) mounted to a lower end of the tube (40). The bottom-hole assembly (42) includes an outwardly facing sealing surface (54). A "free" jet pump assembly (55) is included having a pump body (56) formed for sliding receipt in the tube (40) and the pump receiving passage (49). The pump body (56) includes a lower seal (60) mounted to an inwardly facing surface (62) of the jet pump assembly (55) for sealing engagement with the outwardly facing sealing surface (54) of the discharge port (51) to permit discharge of exhausted production fluid from the jet pump assembly (55) through the discharge port (51).

  • Patent number: 5509482
    Abstract: A perforation trigger bypass conduit assembly (10) for a well perforation gun (17) positioned in a well casing (12) at a down-hole location below a tubular completion assembly (16). A pressure sensing device (20) senses a detonation pressure of fluid communicated from a pump (21) through bypass conduit assembly (10) to the sensor (20). The sensing device (20) triggers the gun upon sensing a pressure surpassing a predetermined value, which perforates the casing (12). The bypass conduit assembly (10) is formed to enable blocking of the bypass conduit assembly (10) after triggering of the perforation gun (17) to prevent pumping of production and power fluid back into the formation upon severing of a portion (34) of the conduit assembly (10). Blocking can be effected by removing a member (25) which contains a passageway (51) forming part of the bypass conduit assembly (10) and replacing the removable member (25) with a passageway-free insert member (35).
